# This input file reproduces the output in Juhlin (1995) Figure 6a.
# Note that the source in Table 1 in Juhlin (1995) is given as g(t), but should be f(t)
# be f(t), i.e. the derivative of the Gaussian (dg)
# Since the dg source waveform is defined by its avg frequency content
# favg should be set to 24.15 Hz to correpsond to alpha=10000 in
